<h4 class="subsection">6.59.31 x86 Built-in Functions</h4>

<p>These built-in functions are available for the x86-32 and x86-64 family
of computers, depending on the command-line switches used.
</p>
<p>If you specify command-line switches such as <samp>-msse</samp>,
the compiler could use the extended instruction sets even if the built-ins
are not used explicitly in the program.  For this reason, applications
that perform run-time CPU detection must compile separate files for each
supported architecture, using the appropriate flags.  In particular,
the file containing the CPU detection code should be compiled without
these options.
</p>
<p>The following machine modes are available for use with MMX built-in functions
(see <a href="Vector-Extensions.html#Vector-Extensions">Vector Extensions</a>): <code>V2SI</code> for a vector of two 32-bit integers,
<code>V4HI</code> for a vector of four 16-bit integers, and <code>V8QI</code> for a
vector of eight 8-bit integers.  Some of the built-in functions operate on
MMX registers as a whole 64-bit entity, these use <code>V1DI</code> as their mode.
</p>
<p>If 3DNow! extensions are enabled, <code>V2SF</code> is used as a mode for a vector
of two 32-bit floating-point values.
</p>
<p>If SSE extensions are enabled, <code>V4SF</code> is used for a vector of four 32-bit
floating-point values.  Some instructions use a vector of four 32-bit
integers, these use <code>V4SI</code>.  Finally, some instructions operate on an
entire vector register, interpreting it as a 128-bit integer, these use mode
<code>TI</code>.
</p>
<p>In 64-bit mode, the x86-64 family of processors uses additional built-in
functions for efficient use of <code>TF</code> (<code>__float128</code>) 128-bit
floating point and <code>TC</code> 128-bit complex floating-point values.
</p>
<p>The following floating-point built-in functions are available in 64-bit
mode.  All of them implement the function that is part of the name.
</p>
<div class="smallexample">

<dd><p>Generates the <code>pause</code> machine instruction with a compiler memory
barrier.
</p></dd>

<p>The following floating-point built-in functions are made available in the
64-bit mode.
</p>
<dl compact="compact">

<dd><p>Similar to <code>__builtin_inf</code>, except the return type is <code>__float128</code>.

<p>The following built-in functions are always available and can be used to

<dt><a name="index-_005f_005fbuiltin_005fcpu_005finit-1"></a>Built-in Function: <em>void</em> <strong>__builtin_cpu_init</strong> <em>(void)</em></dt>
<dd><p>This function runs the CPU detection code to check the type of CPU and the
features supported.  This built-in function needs to be invoked along with the built-in functions
to check CPU type and features, <code>__builtin_cpu_is</code> and
<code>__builtin_cpu_supports</code>, only when used in a function that is
executed before any constructors are called.  The CPU detection code is
automatically executed in a very high priority constructor.
</p>
<p>For example, this function has to be used in <code>ifunc</code> resolvers that
check for CPU type using the built-in functions <code>__builtin_cpu_is</code>
and <code>__builtin_cpu_supports</code>, or in constructors on targets that
don&rsquo;t support constructor priority.
